I have wondered why everyone on here was not as supportive of them as other companies....today I found out why...I have spent over a 100 grand with them....and even bragged about their products on here.....after the treatment I got from them today....I am going to take every piece of ats performance products off of my truck and that will be that.....what horrible customer service and treatment....it makes me proud that guys like Keven from K2 diesel performance are in business....he is great to deal with and actually cares about the people he deals with, and knows the products he sells. What are these companies thinking when they think we are all just disposable? We have a lot of influence on their products...especially on here....I for one will never recommend anything they provide...Just my opinion.
